地铁施工测量精度的影响因素及技术应用

Influencing Factors and Technical Application of Subway Construction Measurement Accuracy

地铁的施工风险大且难度高,再加上地铁的设计施工多是在城市发展到一定阶段后进行的,除地理环境因素外,还将面对复杂的地埋管线及其他人工构筑物。为了顺利完成地铁隧道贯通,降低地铁施工对环境的影响,需切实保障地铁施工测量安全,这也是最基本的施工管理要求。文章首先就地铁施工测量特点及内容加以概述,分析了施工测量精度的影响因素,并探讨了地铁施工测量技术应用,旨在为地铁施工测量的顺利开展提供帮助。

The construction of the subway is risky and difficult.In addition,the design and construction of subway are mostly carried out after the development of the city to a certain stage.In addition to geographical environmental factors,complex buried pipelines and other artificial structures will also be faced.In order to successfully complete the subway tunnel penetration and reduce the impact of subway construction on the environment,it is necessary to ensure the safety of subway construction measurement,which is also the most basic construction management requirement.This paper first summarizes the characteristics and contents of subway construction measurement,analyzes the influencing factors of construction measurement accuracy,and discusses the application of subway construction measurement technology,aiming to provide help for the smooth development of subway construction measurement.
